The idea
A study names the variables it will measure — what is manipulated, what is expected to change, and what may sit between them.
In practice
An intervention, an outcome, and the motivation that may connect them.
Where people slip
A variable that is expected to matter and is not measured cannot be examined afterwards. The list is fixed early for that reason.
